Built for Shops That Have Outgrown Excel
Spreadsheets weren't designed for tracking fabrication inventory or calculating real BOM costs. One broken formula can turn a profitable job into a loss.
In Excel, you're responsible for building and maintaining the system: tabs, formulas, references, and workarounds that break as soon as something changes.
Arc Manager replaces messy spreadsheets with a structured, offline system designed for how fabrication shops actually work. You enter materials, hardware, and assemblies once — and the relationships are handled automatically.
